tectonic··on A DIY ‘bionic pancreas’ is changing diabetes care
That’s horrible, I’m sorry for your loss.
tectonic··on Ask HN: Tell us about your project that's not done yet but you want feedback on
This is super cool, thank you for making it!
tectonic··on Show HN: I spent 2 years building a personal finance simulator
ProjectionLab is fantastic, thank you for making it.
tectonic··on Tell HN: "I don't care about cookies” extension bought by Avast, users jump ship
A decade ago I wrote an extension called SelectorGadget (https://selectorgadget.com/). It's effectively unmaintained, but it still works and people still use it. I make no money from it and never have. Every few months someone tries to buy it from me, and I ignore them because I don't want to f** over my users. But there are a lot of extensions out there and maybe their owners care less, or find themselves in a moment of financial hardship and they sell.
tectonic··on Jeff Bezos announces $3.4B NASA contract to land astronauts on lunar surface
Actual press release: https://www.nasa.gov/press-release/nasa-selects-blue-origin-...

NASA needs multiple lander options; putting all their cards on a lunar Starship landing was always a bit ridiculous, even if it seems reasonably likely to happen. So if you want the Artemis program to actually succeed, this is likely a good thing. However, with Congress in a deadlock around the debt ceiling, and SLS costing $4B per launch, this is only going to add to Artemis's serious funding challenges.

If you're interested in the space industry in general, I'll cover this more next week in the weekly Orbital Index newsletter (https://orbitalindex.com) which I co-author with blach.

tectonic··on Build your own agents which are controlled by LLMs
Cool! I made something similar that lives in a browser extension: https://github.com/cantino/browser-friend
tectonic··on Introducing Agents in Haystack: Make LLMs resolve complex tasks
I just released something like this embedded in a browser extension. Except the prompt includes a TypeScript interface that GPT4 is asked to follow. Works very well and reliably uses tools like Calculate, RequestDOM, etc.

tectonic··on Compostable fast-food packaging can emit volatile PFAS
Yes agreed. Teflon is shorthand for all of the fluorinated hydrocarbons in my mind. I know they’re not identical but they’re close enough and most if not all will end up being found to be toxic.

The problem is a lack of a precautionary principle— manufacturers can change one molecule and re-market their product and groups like the EPA have to do extensive research on each new variant to show danger. Molecules are assumed safe and marketable until shown otherwise by underfunded agencies. It’s insane.

See this site: https://www.foodpackagingforum.org/fccmigex
tectonic··on Compostable fast-food packaging can emit volatile PFAS
Glass, metal, ceramic, old fashioned plastic. The problem is generally packaging materials not things like Tupperware or glassware.
tectonic··on Compostable fast-food packaging can emit volatile PFAS
Yup: https://www.consumerreports.org/health/food-contaminants/dan...
tectonic··on Compostable fast-food packaging can emit volatile PFAS
Yes to both of those.
tectonic··on Compostable fast-food packaging can emit volatile PFAS
Just. Stop. Putting. Teflon. On. Everything.

Figuring out what does and does not have PFAS on it to protect my family is exhausting and infuriating. I’ve emailed with manufacturers, sent stuff to labs; basically, no one seems to know how much materials like this are used on every day products.

tectonic··on TaxyAI: Open-source browser automation with GPT-4
Oh man, I have been working on an extension like this over the last few days. Congrats on your release!
tectonic··on Show HN: Moonshine – open-source, pretrained ML models for satellite
You should definitely submit this to https://github.com/orbitalindex/awesome-space#earth!
tectonic··on Khan Academy integrates GPT-4 as every student’s customized tutor
A Young Lady's Illustrated Primer
tectonic··on OpenAI Becomes ClosedAI
OpenAI, the clean coal of machine learning.
tectonic··on Very Long-Term Backup (2008)
Is Long Now still going strong? It feels like I haven’t heard much from them in a while. Still a big fan.

Edit: and yes, I know they are philosophically opposed to doing anything quickly.

tectonic··on Kerbal Space Program 2 Early Access Gameplay Trailer
Those rockets didn't have nearly enough boosters.
tectonic··on Show HN: Indian Space Progress, the world’s only blog dedicated to Indian space
Jatan’s other newsletter, Moon Monday, is also excellent!
tectonic··on For your next side project, make a browser extension
Mostly with a bunch of handy quick tools that in the past I would have put in bookmarklets.
tectonic··on For your next side project, make a browser extension
I have a personal browser extension that I use as a grab bag of assorted tools and fixes for sites that annoy me. It's half way between a userscript, a bookmarklet directory, and a UNIX shell, with little commands that run automatically on certain sites or operate on the DOM, and can pipe output to other commands. Here's a very old video of it in action: https://vimeo.com/118090094 (It's no longer open source because I don't want to have to maintain it for other people.)
tectonic··on Show HN: Val Town – A Cloud Scripting Site
I ran a website called JavaScript Town when I was in high school in the 90s. Probably should have kept that online.
tectonic··on 2022 Climate Tech VC funding totals $70.1B, up 89% on 2021
And this is definitely incomplete, so the real number is probably significantly larger. I know of multiple climate tech deals not present in the data they cite.
tectonic··on Ask HN: Who is hiring? (December 2022)
Overview Energy | Engineering | Northern Virginia / DC | Full Time | ONSITE

Overview Energy is hiring Hardware Engineers, a Photovoltaic Lead Engineer, and a Space Systems Lead. We're developing next generation, high-power GEO satellites for the Starship era. We’re VC-backed and just getting started.

tectonic··on Beaming solar energy from space
I disagree. The currently envisioned approaches are impractical due to in-orbit assembly needs, but there are other options.
tectonic··on $ rm Important.txt (uh oh)
I was just thinking that I'd write a command for this if it didn't exist already. But it does: https://apple.stackexchange.com/a/50852
tectonic··on Ask HN: Who is hiring? (July 2022)
MethaneSAT is quite important!
tectonic··on Ask HN: I want my next startup to be in space tech. Where do I start?
I author Orbital Index (https://orbitalindex.com) weekly about the space industry. Hit me up if you want to chat.
tectonic··on I accidentally loaned all my money to the US government
I think this is exactly right.
